a y rclims (citen-tan` vAn object kof my invention is to producen aV tightly` wrapped package when this isfdesirable :in preference to a loosely Wrapped package as .now produced bythe existingxtype of' automatic A wrapping machine in universaluse, by*y which a roll of paper' or cellophane is'used to Wrap packages such as bread and thelike.

A further object of my invention-is tocontrcl the idler ,roller which functions by rotatively pressingl against the perpendicular lsheets of wrapping material used in making loosely wrap-V pcd packages,l by rotating the idlerrroller in the opposite directionl to the ,direction of the Wrapping material and thereby -cause a certain amount of retardation Aor resistance to the wrapping materialJ to cause i-t to makea tightly Vwrapped package. r This function being carried out Without changing any ofthe parts of the eX- isting machine. l j v Y lThe mechanism describedv hereinto, accomplish either a loose or tight wrapping of packages yis so constructed that it does not interfere with `any of the parts ofthe existing construction of an automatic wrapping machine excepting in the control of the idler rollerby means of my mechanism and the useof arhorizontal sprocket chain positioned on the top side of. the Y' `by sprocket chain 23. 'bracket-or housing 2t fon which the roller 30 is rotatably mounted, the collar' and the :hub'oi machine. This chain although usedto drive other parts of the-machineV is adapted-for engagement with a sprocket Wheel of ,my mechanism for driving the same.

In the accompanying drawings;-

,Figure 2a is a partial top plan view of the guide roller, n y Figure 3 4is a rnodication` of'th'e'invention and Y Y Figure 4 vis a further modication of the invention. Y -In Fig. l the shaft I rotates in its housing y2, a collar 2 is on the endof the shaft'WithVaset .screw 3 for securing thel collarto theshaft so as to prevent displacement off a ycombination .sprocket wheel andspur gear wheel .fi,'f"loosely mounted on the shaftbetween the collar 2f^`and the` end of thevhousin'g 2,V the lhousingbeing mounted onV a base 3 I, which is bolted down` onvan extension bracket 32 of the originalmachine. V'An aperture 5 is bored inthe shaft and a'sprirlg button is mounted on the hub of V'the combinationv sprocket and spur gear Wheel with the `an l annular recess rwithout interference with these otherparts. At therother endy of the shaft vI ismounteda small sprocket wheel 8 and Aa large sprocket Ywheel 9,

integralfwith one another, and pinned `fast to the Yshaft Iwithfa taper pin it and adjacent to the other end of housing 2.

A second housing I I is mounted on the plate I the spur gearwheel lli its teeth I5 meshingv with the teeth of `spur gear wheel fit mountedi-,on

shaft I, the hub i@ of the spur gear Wheel I4 has spanner. device f it which controls thev slidable operaticn,the Spanner device I8 with its handle I9 is swiveledby screw 20 for moving the teeth i5 and 41'! in yand out of mesh. In order to prevent displacement of gear It from its shaft alcollar` 2l is pinned thereon with a taper pin 22 and adjacent the `housing ,is a collar 23 also vpinnedvto the. shaft- I2 with a taper pin 24.

Mounted-onlthe other end of the shaft ,I2 is a sprocket Wheelpinned thereon by taper pin 26, a sprocket chain 25 connecting sprockiets4 8 and.'V @n u The shaft Irotates sprocket gear Wheel 9 con-` nectedas shown in Fig.V 2 with sprocket'wheel 21 Figure 2a` shows a Vclamp V:While the end of thevbutton l is Withdrawn from the aperture 5 bored vin shaft I.- The arrow in vFigure 1 points to the right which is the direction in which the sprocket chain 3'travels' in the original machine and withfwhich the sprocket gear wheel. llfisfadapted to mesh.. rWhenthe machine is started the sprocket Wheel lis rotated tothe right` `andthf-z-spur gear wheel ll" .also revolves .tothe` right'and is meshed With spur gear M `so thatthe shaft'll is therebyr rotated to the lett'and'inV which direction the sprocket wheel 5 turns.;` -Thes'procket chain 26"', in turn, drives :sprocket wheel Y8 andthe shaft vI to thexleft thereby'` turning .the large `sprocket wheel 9 -to the left and thechain 23 drives sprocket Wheel 21 whichl in turn drives the roller 3@ Vto the left for yloose .wrapping of packages.

This is brought about by reason of the button being turned so thatits end l is Withdrawnfrom the aperture 5 bored into shaft I andthe intermeshing of the rspurgear'vvheels @"and i4; :f

i 'For tight wrapping ofy packages the 'Spur gearjl 4 is disengaged by the spanner device I8 from spur gear 4 and the button 6 is turned to allow its il to receive therein vthe,

' means of slidable bevelgears.

sprocket chain 3 running horizontally in the:A

original machine, but as above stated shaft I when connected with the end of the buttonpin T" becomes an entirety revolving allits attached mechanisms to the right. The roller 3U rotates therefore to the right causing by suchactionY a retardation or resistance against the. wrapping, material as it is fed forward for wrapping purposes in the original machine andthus-causes theproductionof a tightly wrapped package. Wilththe addition of-my mechanism to the originalmachine aloose or tight package wrappingis effected.`

The mechanism described above'may-be modified as shown in Figures and 4.

Figure 3 discloses a mechanismwhich'v-ll turn shaft 33` either' to the right ori` to the left by housing 34 is attached to bracket 3 l shownin-Fig. 2- connecting Ytherewith and supported thereby are arms 35 with housings 3S at their ends'. for housing shaft 33?. Collars 31mounted on the shaft-to-preverit 'displacement of the housings', splines 38setV into the shaft, slidably mounted bevel.`;gears39`v mounted on` shaft 33, an elongated collar lpinned" by taper pin 4l to shaft 33 toseparate the bevel Vgears for proper engagement with cc-mtrallV bevel wheel engages withV the horizontal.sprocketl chain of the machine proper and travels Vto the right .at all times consequently the centraL bevel'gear always travels to the right.` Thereforeif shaft 33 is to travel to' the right the upper gear 39 is disengaged from the centralv bevel geaxt'while the lower. bevelgear 39 is meshed with-it.A This will turn the lower bevel gear'to the right and transmit this direction: to lower bevel wheel 5U pinned toshaft: 33' and supported by its housing 5| which is supported'by. arm 52 attached to housing. 53 in whichv rotates the roller. shaft. l to; which. is pinnedy the roller 55 the end of whiclrissupported by a V shaped screw in the V shape; aperture 56. At the inner end of the rollerxisthe bevel wheel. 51

. pinned: to the shaft withtaperr. pin. 58. Y

To turn the shaft. 331'- to the leftf the spinner wrench lever moves theloweribeveligear s-'out of mesh' from: the central gear I2, (this isV always done when the machine `is stopped)V the upper bevel gear 39 is then thrown into mesh .with the central bevel gear 4-2-and` as this central gear thrown. out ofmesh Vwith the central' gear, the i shaft 33 will then rotate to the right and the roller to the left for loose wrapping of packages.

In Figure 4 we deal with disk and friction wheels. The disk 59 is fastened to shaft 60 by pin M and rotates inthe housing 62. At the end of theV shaft Gti'y isv the sprocket Wheel 48 (see Fig. 3)

arms`63 with housings 64 at each end thereof inV lbro'lwri. away at itslower end for the reason that the sameconstructionfor the extension of shaft i5 isi-asis shown inFig. 3 at the end of the shaft 'Repetition'. was thought unnecessary'in this respect' as it is amply shown in Fig. V3.
